Questione giuridica chiave
Whether the cantonal court's assessment of the facts and refusal to order further evidence was arbitrary or violated the right to be heard.
Decisione estratta
The appellant did not show any insustainable factual assessment or procedural application; the complaints were unsubstantiated and no violation of the right to be heard was established.
Motivazione estratta
The Court held that arbitrariness requires a result that is manifestly untenable, not merely arguable. The appellant only opposed his own view to that of the cantonal court. Given the summary nature of marital-protection proceedings and the limited evidentiary standard, the refusal to open enquiries was not unconstitutional.
